Links to private WhatsApp groups appear through Google

WhatsApp groups appear when searching through Google again. Hence, anyone can find out a private WhatsApp group and join it after searching on Google.
This was first discovered in 2019 and appears to have been fixed last year after being made public.
Another old issue, which also seems to have been fixed, but has reappeared, is that user accounts appear in search results.
Due to this problem, people can view their phone numbers and profile pictures with a simple Google search.
By allowing indexing of group chat invitations, WhatsApp provides many private groups on the web where anyone can access their links using a simple Google search query.
The person who finds these links can join groups and can also see the participants and their phone number with the posts posted in those groups.
Cyber ​​security researcher Rajshekhar Rajaharia reported indexing group chat invitations on WhatsApp through Google.
Indexing seems to have started again recently, and there were over 1,500 group invite links available in search results at the time of writing.
Some of the links indexed by Google lead to WhatsApp groups for sharing pornography, and in a few other cases there were links to WhatsApp groups dedicated to a specific community or interest.
People who haven’t been invited can easily join groups using links.
It should be noted that this is not the first time that this issue has occurred, as in November 2019, WhatsApp group chat invitations were found in Google search results.
The issue was reported to Facebook by a security researcher, although it was resolved shortly after being covered by multiple media outlets in February of last year.
WhatsApp fixed the group chats indexing issue by adding the meta noindex tag to invite links. However, recent links include the noindex meta tag.
It appears that the group chat links revealed in 2019 are not visible through Google. So it may be a different problem leading to similar results or a change that inadvertently led to the emergence of the old problem.
In addition to the group invite links, it looks like WhatsApp has once again allowed Google to index user accounts, allowing anyone to chat with a user or look at their profile picture.
WhatsApp user profiles are again accessible through Google, as the search engine has indexed more than 5,000 profile links. There are also links to users who have allowed anyone within the messaging app to see their profile photos and statuses.
